Conditional survival in patients with esophageal or gastroesophageal junction cancer after receiving various treatment modalities.

ABSTRACT:

Background

To estimate the adjusted conditional overall survival (COS) in patients with esophageal cancer after receiving various treatment modalities via a national population-based database, and to investigate the possible time-dependent effects.

Materials and methods

Eligible patients diagnosed with esophageal cancer between 2000 and 2016 were identified from the Surveillance, Epidemiology, and End Results (SEER) registry. The Kaplan-Meier method was used to calculate conventional survival time. The inverse probability of treatment weighting method was used to estimate the adjusted COS in patients receiving different treatment modalities. Landmark analysis was employed to investigate the possible time-dependent effects of different treatment modalities in patients who had
